Barbados is small enough that getting around is rarely a headache. The road network is extensive and most of the island is reachable by bus, taxi, or rental car within 30–40 minutes from anywhere on the west or south coast.
The best and cheapest option is the bus. There are three kinds: government-operated public buses with the most extensive routes, a privately operated minibus system, and route taxis (shared minivans that follow fixed routes). All are inexpensive and can get you to most parts of the island.
Renting a car gives you the most flexibility. None of the local agencies is affiliated with a major international chain, but most will pick you up from your hotel. You will need a temporary driving permit, which your rental agency can arrange for a small fee. Remember that Barbados drives on the left.
Taxis are widely available and fares are government-fixed — but vehicles are unmetered, so agree on a price before you set off, especially for longer sightseeing runs. Bicycles can be rented in Hastings and Maxwell if you want to explore at a slower pace.
Grantley Adams International Airport is on the southern coast, 16km southeast of Bridgetown. Most car rental agencies will collect you from there; otherwise taxis and local buses are both available at the arrivals exit.
